Calculate the margin of error in estimating a binomial proportion $p$ using samples of size $n=100$ and the values of p given in Exercises $15-19 .$ What value of p produces the largest margin of error? $p=.1$
Added by Elena C.
Step 1
The formula for the standard error of the proportion is: $$SE=\sqrt{\frac{p(1-p)}{n}}$$ For $p=0.1$ and $n=100$, we have: $$SE=\sqrt{\frac{0.1(1-0.1)}{100}}=0.03$$ Show more…

Calculate the margin of error in estimating a binomial proportion $p$ for the sample sizes given in Exercises $11-14$. Use $p=.5$ to calculate the standard error of the estimator, and comment on how an increased sample size affects the margin of error. $n=100$

Calculate the 95% margin of error in estimating a binomial proportion p using samples of size n = 169 and the following value for p. (Round the answer to four decimal places.) p = 0.9 = ? Consider that for n = 169 and values of p equal to 0.1, 0.3, 0.5, and 0.7 the values of the margins of error are 0.0452, 0.0691, 0.0754, and 0.0691. What value of p produces the largest margin of error? p = 0.1 p = 0.3 p = 0.5 p = 0.7 p = 0.9
